[PATCH ghak59 V1 2/2] audit: watch: simplify audit_enabled check

Check the audit_enabled flag and bail immediately. This does not change the functionality, but brings the code format in line with similar checks in audit_tree_log_remove_rule(), audit_mark_log_rule_change(), and elsewhere in the audit code.
